parameters are so many signals revealing its internal structure, and the
analysis of which will provide indications on the internal organization
and mechanisms of the aquifer. The following curve (Figure 82), where the
smallest rainy period results in a discharge peak, indicates that the system
has little storage, as two months are enough to drain it. In addition, the
breaks in the slope observed during the emptying of the system following
discharge peaks refl ect the existence of two compartments, confi rming the
geologic and structural conditions of the system (Figure 83).
